The various implementations provide a very versatile watch and record environment for the user.

Description

• This application claims the benefit of U.S. patent application No. 60/089,487, filed Jun. 16, 1998.
BACKGROUND OF THE INVENTION
• This invention relates to interactive television program guides, and more particularly, to television program guides that allow users to record one program while simultaneously watching a different program.
• Interactive program guides are typically implemented on set-top boxes. The program guides implemented on set-top boxes allow users to view television program listings. In addition, some program guides allow the user to select a program to be recorded. When the selected program begins, the program guide tunes the set-top box to the channel showing the program and directs a videocassette recorder (“VCR”) to begin recording. At the end of the selected program, the program guide stops the recording process.
• A significant disadvantage to the program guides that are currently available is that they are generally based on set-top boxes that contain one tuner (although set-top boxes containing two tuners have been proposed). A program may be selected for recording using such one-tuner program guides, however, a viewer is unable to watch one program while simultaneously recording another.
• What is needed is a more sophisticated program guide that can perform an allocation function amongst multiple tuners or a single tuner in conjunction with a RF bypass switch inside a set-top box or alternatively, outside the set-top box to allow a viewer to watch one program while simultaneously recording another program.
• It is therefore an object of the present invention to provide an interactive television program guide system which allows a user to record one program while simultaneously watching another program.
SUMMARY OF THE INVENTION
• The present invention provides the user of an interactive television program guide with the ability to watch one program while simultaneously recording another. The user may select a television program to be recorded by viewing the interactive television program guide's program listings display screen and making a selection using a remote control device. The selection is then stored in memory that resides in the set-top box or some other suitable device such as a satellite receiver, an advanced television with a processor and memory or a computer.
• If the set-top box is equipped with multiple tuners, the interactive television program guide will allocate one of the tuners for recording the program when it is time for the program to start. However, if all of the tuners are in use, which may be the case if the viewer is watching one program and using a picture-in-picture (“PIP”) feature to view another program or to display additional text or graphics by using some other secondary tuner function feature that requires a tuner to operate, the interactive television program guide may allocate a tuner for the recording function if the user indicates that he is no longer interested in using the PIP or another secondary tuner function or if the tuner allocation scheme dictates it do so. Alternatively, if the set-top box is equipped with two tuners, one may be dedicated for television viewing and interactive television program guide user features, while the other tuner may be dedicated for recording use only.
• The present invention may also be practiced using a set-top box system having a single tuner and a radio-frequency (“RF”) bypass or digital switch. With such a system, the interactive television program guide allocates use of the single tuner output and controls the switch output to provide a watch and record environment for the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
• FIG. 1(a) shows an illustrative interactive televisionprogram guide system100 in accordance with the present invention.Main facility102 contains aprogram guide database104 for storing program guide information such as television program guide listings data, pay-per-view ordering information, television program promotional information, etc. Information fromdatabase104 may be transmitted to multipletelevision distribution facilities110 viacommunications link120. Only onesuch facility110 is shown inFIG. 1 to avoid over-complicating the drawing.Communications link120 may be a satellite link, a telephone network link, a cable or fiber optic link, a microwave link, a combination of such links, or any other suitable communication path. If it is desired to transmit video signals overlink120 in addition to data signals, a relatively high bandwidth link such as a satellite link is generally preferable to a relatively low bandwidth link such as a telephone line.Television distribution facility110 is a facility for distributing television signals and data to users, such as a cable system headend, a broadcast distribution facility, or a satellite television distribution facility.
• The program guide information transmitted bymain facility102 totelevision distribution facility110 includes television program listings data for current and future television programs. The television program listings data for each program preferably includes the title of the program, the channel for the program, a scheduled broadcast time (start time) and an ending time or the duration of the program. Other typical program listings data includes ratings, critics ratings, descriptions, genres (sport, movies, children, etc.), actors, etc. Transmitted program information may also include advertising information and pay program data such as pricing information for individual programs and subscription channels, telephone numbers for placing orders that cannot be impulse ordered, etc.
• Television distribution facility110 distributes television programming and program guide information to theuser television equipment106 of multiple users viacommunications paths108. For example, television programming may be distributed over analog television channels and program guide data may be distributed over an out-of-band link onpaths108. Data distribution may also involve using one or more digital channels onpaths108. Such digital channels may also be used for distributing television programming and other information. Multiple television and audio channels (analog, digital, or both analog and digital) may be provided to set-top boxes112 viacommunication paths108. If desired, program listings and other information may be distributed by one or more distribution facilities that are separate fromtelevision distribution facility110 using communications paths that are separate frompaths108.
• Certain functions such as pay program purchasing may require set-top boxes112 to transmit data totelevision distribution facility110 overcommunications paths108. If desired, such data may be transmitted over telephone lines or other separate communications paths. If functions such as these are provided using facilities separate fromtelevision distribution facility110, some of the communications involving set-top boxes112 may be made directly with the separate facility.
• Each user has user program guide equipment that acts as a receiver. The user program guide equipment is typically a set-top box such as set-top box112, but which may be other suitable television equipment into which circuitry similar to set-top box circuitry has been integrated. Program guide data is distributed to set-top boxes112 periodically, continuously or on demand.Television distribution facility110 may also poll set-top boxes112 periodically for certain information (e.g., pay program account information or information regarding programs that have been purchased and viewed using locally-generated authorization techniques).Main facility102 preferably contains a processor to handle information distribution tasks. Each set-top box112 preferably contains a processor to handle tasks associated with implementing a interactive television program guide application on the set-top box112.Television distribution facility110 may contain a processor for tasks associated with monitoring a user's interactions with the interactive television program guide implemented on set-top boxes112 and for handling tasks associated with the distribution of program guide data and other information touser television equipment106.
• Each set-top box112 is typically connected to an optional recording device such as videocassette recorder (VCR)114 or other suitable recording device, so that selected television programs may be recorded.VCR114 may be connected to television116 (or other suitable viewing device such as a monitor) or set-top box112 may be connected to television116 (or other suitable viewing device). To record a program, set-top box112 tunes to a particular channel and sends control signals via infrared (IR)transmitter200, other suitable control paths such as a hard-wired link orserial bus201 toVCR114. The control signalsdirect VCR114 to start and stop recording at the appropriate times.
• During use of the interactive television program guide implemented on set-top box112, television program listings and other information may be displayed ontelevision116. Such interactive television program guide displays may be overlaid on top of a television program to which the user has tuned with set-top box112 or may be displayed in place of such a program. Each set-top box112,VCR114, andtelevision116 may be controlled by one or moreremote controls118 or any other suitable user input interface such as a wireless keyboard, mouse, trackball, dedicated set of buttons, voice recognition system etc. Remote controls such asremote control118 have various buttons that may be pressed by the user such as cursor keys (for on-screen movement of a highlighted region, scrolling functions, etc.), an enter key (for making a selection), channel number keys (for selecting functions related to user preferences), etc.
• FIG. 1(b) shows alternative devices that may be used in implementing the interactive television program guide. The interactive television program guide may be implemented on user program guide equipment that includes a set-top box, advanced television receiver with a microprocessor and memory, a personal computer with or without one or more tuners, a satellite receiver, a high definition television (“HDTV”) receiver, or any other suitable television reception and data processing device. A suitable personal computer arrangement may contain a tuner card that contains suitable analog and digital tuning circuitry to perform the simultaneous watch and record features. A tuner card may contain two analog tuners that both receive television program signals from the television input signal and are controlled by the interactive television program guide. Typically a digital tuner for the interactive television program guide system may contain an analog tuner, a decoder such as a Motion Pictures Experts Group (“MPEG”) MPEG-2 decoder, a demodulator such as a quadrature amplitude modulation (“QAM”) demodulator, and a demultiplexer such as a MPEG-2 demultiplexer that is used to extract the portion of the television input signal that is desirable to the user and corresponds to a particular television program or channel. Alternatives for the recording device include a videocassette recorder, a digital versatile disk or digital video disk (“DVD”) player with recording capabilities, a digital storage device such as a disk drive or other suitable digital storage device that may or may not be part of the computer, or any other suitable recording device. The recording device may also be a videocassette recorder controlled by the computer. Alternatives for the viewing device include a television, a monitor with or without an attached computer, or the viewing equipment portion of a personal computer-television (PC/TV). The viewing device may also be an analog or digital television.
• FIG. 2(a) shows an illustrative two-tuner set-top box112. Thetelevision input signal206 may be received from a cable connected to a cable system headend or from an antenna that receives satellite television transmissions. Television signals may also be received that are distributed, for example, by terrestrial wireless communications systems such as microwave-based communications systems or the like. If desired, television signals may be received from conventional broadcast television systems. Television-like signals may be received over the Internet (e.g., using video compression techniques). Television signals from these sources or any other such suitable sources may be combined if desired. Television signals may be analog or digital (e.g., in the MPEG-2 format or the like). A television input signal that has not been processed by a tuner or decoder in the program guide equipment is referred to herein as a raw signal.
• The unprocessed television input signal online206 is provided to set-top box112. The unprocessed television input signal online206 is then received bytuner202 andtuner204 which process this signal by decoding it and tuning to desired television channels. The television input signal online206 is typically an analog television signal and the invention will generally be described in this context. However, the principals of the present invention also apply to set-top boxes that receive digital television signals as well. The principals of the present invention apply to satellite receivers, cable set-top boxes, and other devices suitable for the reception of television signals such as microwave television receivers, or broadcast television system receivers. However, for clarity the present invention will be described primarily in the context of cable set-top boxes. Tuner outputs208 and210 of each tuner are respectively connected to audio/video output1 and audio/video output2 of set-top box112. Audio/video output1 and audio/video output2 may be connected to external devices such as either a television or VCR. Formats for audio/video output1 and audio/video output2 may include RF or baseband analog, MPEG-2 carried on an IEEE 1394 bus, or any other suitable format.
• In this example, audio/video output204 is connected toVCR114. Accordingly, with the arrangement ofFIG. 2(a), the interactive television program guide always uses the same tuner for recording functions, becausetuner204 is dedicated for that purpose. However,VCR114 may be connected to either audio/video output1 or audio/video output2 so that ifVCR114 is connected to audio/video output1,tuner202 will be used exclusively for recording.
• FIG. 2(a) also shows that the interactive television program guide system may include anexternal IR transmitter200 for communicating withVCR114.External IR transmitter200 receives interactive television program guide command signals from set-top box112 online212. Although inFIG. 2(a) and other drawings,IR transmitter200 is depicted as being external to the set-top box112, this configuration may be modified if desired by using a set-top box that includes an internal IR transmitter capable of transmitting an infrared signal at an optimal trajectory such that it is effectively received by external devicessuch VCR114 andtelevision116.IR transmitter200 may be optimally positioned so thatVCR114 will receive the IR signal effectively. Alternatively, the interactive program guide system may include two IR transmitters, one forVCR114 and one fortelevision116 or other equipment for communicating with the recording device such as optionalserial bus201. The interactive television program guide command signals online212 that are provided toIR transmitter200 allow channel selection requests and VCR start and record commands to be sent from the interactive television program guide in set-top box112 toVCR114. The interactive television program guide commands that are sent toVCR114 are based on the user's interactions with the interactive television program guide (i.e., to select programs for recording, etc,).
• FIG. 3(a) is a flow chart showing steps involved in using an interactive television program guide system having a set-top box configuration such as shown inFIG. 2(a). Atstep300, the interactive television program guide provides the user with an opportunity to select a program to be recorded at some later time. The user may select a program to be recorded from a interactive television program guide screen such as interactive television program guideprogram selection screen400 ofFIG. 4(a), which the interactive television program guide displays on the user's television. By entering a selection usingremote control118, the user may select a program to be recorded. The user may enter a selection intoremote control118 by using the up and down cursor buttons onremote control118 to highlight the desired selection with a highlight region such ashighlight region402. In the example depicted inFIG. 4(a), program 10, is being selected for recording at 7:30 onchannel 4. The user may initiate recording by pressing a remote control “record” button or by pressing an “OK” button followed by appropriate responses to various on-screen menus generated by the interactive television program guide.
• Atstep302 ofFIG. 3(a), the interactive television program guide sends commands totuner204 ofFIG. 2(a) at the time the program selected afterstep300 is about to begin. These commands allow the interactive television program guide to tunetuner204 to the channel of the program selected for recording.
• Atstep304, the interactive television program guide sends commands viaIR transmitter200 thatdirect VCR114 ofFIG. 2(a) begin recording. Optionally, the interactive television program guide may send commands thatdirect VCR114 to turn on if necessary. Whiletuner204 ofFIG. 2(a) is being used to record the selected program,tuner202 may be used to view any program made available to the user ontelevision input signal206 bytelevision distribution facility110. In addition, the user may use the interactive television program guide without any limitations as to which tuner-related features of the interactive television program guide may be used. This two-tuner set-top box system provides a system by which the user may simultaneously watch one program and record another.
• Atstep306 ofFIG. 3(a), the interactive television program guide sends IR commands toVCR114 at the end of the recorded program. These IR commands instructVCR114 to stop recording. Optionally, the interactive television program guide may send commands thatdirect VCR114 to turn off if necessary.
• FIG. 2(b) shows another illustrative arrangement of a two-tuner set-top box112. The arrangement ofFIG. 2(b) allows the interactive television program guide to allocate whichever tuner is not currently busy for recording a selected program when that program is about to begin.Outputs208 and210 oftuners202 and204 respectively, ofFIG. 2(b) are connected toinputs214 and216, respectively, of switchingcircuitry218.Switching circuitry218 is controlled by interactive television program guide command signals online212.Switching circuitry218 has twooutputs220 and222. Each of the switchingcircuitry outputs220 and222 may be connected to at least one external device such astelevision116 orVCR114. The arrangement ofFIG. 2(b) is similar to the arrangement ofFIG. 2(a), except that the FIG.(b) arrangement has switching circuitry that allows the interactive television program guide to switch tuner outputs so that each external device may receive output from eithertuner202 ortuner204, whereas the arrangement inFIG. 2(a) only allows the tuner outputs to be dedicated to one external device or another. Further, in the configuration ofFIG. 2(b), both switchingcircuitry outputs220 and222 are connected totelevision116 andoutput222 is also connected toVCR114.Output220 is connected to the regular television input andOutput222 is connected to the Picture-In-Picture input or some other auxiliary television input. This configuration allows the user to use secondary functions such as PIP while viewingtelevision116. Alternatively, the picture-in-picture output from one tuner may be combined internally in the set-top box with the processed signal output from the other tuner to create one output that is connected totelevision116.
• FIG. 3(b) shows a flow chart of steps involved in using an interactive television program guide system having a set-top box configured as shown inFIG. 2(b). Beforestep300, a user may use the interactive television program guide to select a particular television program for viewing. The interactive television program guide commands a first non-busy tuner to direct its output totelevision116 for user viewing. Atstep300, the interactive television program guide provides the user with an opportunity to select a program to be recorded. The user may also activate a secondary function for the set-top box tuner such as a picture-in-picture function or the interactive television program guide may utilize that tuner for another secondary function such as collecting program guide data, browsing the Internet, playing a particular music channel, using interactive services or running a background process.
• As shown inFIG. 3c,when a user activates a secondary tuner function, the tuner for that function (e.g., the tuner other than the first non-busy tuner) may perform that secondary tuner function atstep322. Step322 may also involve non-user activated secondary tuner functions such asstep324 that provides support for background processes. A background process supported may be collecting interactive television program guide data. Step324 may be performed, for example, by tuning the other tuner to a channel on which interactive television program guide data is provided frommain facility102 viatelevision distribution facility110 on one ofcommunications paths108 connectingtelevision distribution facility110 touser television equipment106 or more specifically to userprogram guide equipment112. Step324 may also involve using the other tuner to provide interactive services such as enabling Internet browsing atstep326. Internet browsing may involve accessing the Internet by launching a Internet browser and connecting to the Internet using the other tuner over a data channel on one ofcommunications paths108 linking userprogram guide equipment112 totelevision distribution facility110.Television distribution facility110 may contain a server or other suitable equipment for completing a connection to the Internet. Step322 may also involvestep328 of playing a music channel or to obtain information for that channel. Instep328, the other tuner may be used in tuning to a digital music channel provided fromtelevision distribution facility110. Aspects of the use of multiple tuners to obtain in-band information for analog and digital music channels are described in Ellis U.S. patent application Ser. No. ______, filed concurrently herewith (Attorney Docket No. UV-69), which is hereby incorporated by reference herein in its entirety. If desired, the other tuner may be used to provide a picture-in-picture signal atstep330.
• Returning toFIG. 3b,if the user decides to activate a secondary function such as PIP before the interactive television program guide begins to record the program that was selected for recording atstep300, the other tuner is used to provide the secondary function atstep309. Thus followingstep309, both tuners are in use. The user is watching television with the first tuner while the second (other) tuner is being used to provide a secondary function such as PIP. Atstep310, the interactive television program guide processes the request to record the program selected atstep300.
• Atstep312, after the record request is processed the interactive television program guide displays viewer option for secondary function use (PIP cancellation)display screen410 as shown inFIG. 4(b) which provides the user with an opportunity to either initiate the recording process or to continue using secondary functions that involve supplying PIP or additional text or graphics that overlay the display oftelevision116. The user, who is already watching television using the first non-busy tuner, may indicate a desire to continue using the other tuner for secondary functions by selecting “No” on the viewer option for secondary function use (PIP cancellation)display screen410 withhighlight region411. This selection can be made by usingremote control118. If the user selects “No,” the interactive television program guide will continue to direct the other tuner to be used for secondary function use. Alternatively, the user may cancel the secondary function use on the other tuner and may initiate the recording process using the other tuner by selecting “Yes” on viewer option for secondary function use (PIP cancellation)display screen410. If the interactive television program guide does not receive a “Yes” or “No” selection from the user, the interactive television program guide will terminate the secondary function use on the second tuner and proceed with the recording process. Further, if the second tuner is being used for an secondary function such as data collection that requires no user input, the interactive television program guide will automatically terminate that function without displaying a viewer alert screen.
• Atstep314, after the user has chosen to proceed with the recording process, the output of the other tuner is directed toVCR114 by switchingcircuitry218 and used to record the selected program. The interactive television program guide tunes the other tuner to the channel on which the selected program will be broadcast and sends IR commands toVCR114 to start recording.
• If the user decides not to activate a secondary function such as PIP before the interactive television program guide begins to record the program that was selected for recording, the interactive television program guide uses the other tuner to record the selected program at step308. Thus, following step308, both tuners are in use. The user is watching television with the first tuner while the second (other) tuner is being used to record the selected program. If the user attempts to activate a secondary function as shown atpoint311 inFIG. 3(b), the interactive television program guide displays viewer option for secondary function use (recording cancellation)display screen420 atstep316 as shown inFIG. 4(c) which gives the user the option to either cancel the recording process and allocate the other tuner for secondary function use or to continue the recording process and cancel the secondary function request.
• If the user cancels the secondary function request (using, e.g.,highlight region421 ofFIGS. 4(c)) to select “No” in viewer option for secondary function use (recording cancellation)display screen420, the interactive television program guide continues the recording process on the other tuner at step318.
• If the user cancels the record request by selecting “Yes” in viewer option for secondary function use (recording cancellation)display screen420, the interactive television program guide allocates the other tuner for secondary function use atstep320. Instep320, the interactive television program guide sends IR commands toVCR114 to directVCR114 to stop recording.
• FIG. 4(a) shows an illustrative interactive television programguide selection screen400 that may be displayed ontelevision116 when the user enters commands intoremote control118 that direct the interactive television program guide to be displayed. The user may useremote control118 to select a desired program for recording. Interactive television programguide selection screen400 provides the user with an opportunity to view program listings for current and future programs as well as to initiate the recording process by selecting a program to be recorded.FIG. 4(a) depicts an example in which the user has selected program 10 for recording withhighlight region402. Program 10 will be broadcast onchannel 4 at 7:30. This means that at 7:30 the interactive television program guide uses either a set-top box tuner or the internal tuner ofVCR114 to tune tochannel 4 before initiating the record sequence. This record sequence may be performed while the user is watching a television program different from the program being recorded.
• FIG. 4(b) shows an illustrative interactive television program guide viewer option for secondary function use (PIP cancellation)screen410 which acts to alert the viewer to a conflict in tuner allocation and usage.Screen410 may be displayed by the interactive television program guide onuser television116 when the second or “other” tuner chosen by the interactive television program guide to record the selected program is already in use performing a secondary function such as PIP and the first tuner is being used for viewingtelevision116.Screen410 provides the user with an opportunity to continue using the second tuner for the secondary function and to cancel the record request or to cancel the secondary use and to proceed with the record request. If the user still desires to have the program recorded, the user will select “Yes.” The interactive television program guide will then redirect the use of the second tuner and initiate the record sequence. If the user desires to continue using the secondary function, the user will select “No.” The interactive television program guide will then cancel the record request and allow the user to continue using the second tuner for any of the available secondary functions.
• FIG. 4(c) shows illustrative interactive television program guide viewer option for secondary function use (record cancellation)display screen420 which acts to alert the viewer to a conflict in tuner allocation and usage.Screen420 maybe displayed by the program ontelevision116 when the second or “other” tuner chosen by the interactive television program guide is asked to perform a secondary function but that tuner is already busy performing the record function and the first tuner is being used for viewingtelevision116.Screen420 provides the user with the option to continue using the second tuner for recording the selected program and canceling the request for use of the other tuner for performing a secondary function or to cancel the current recording and to process the secondary function request. If the user desires to have the recording process canceled, the user will select “Yes.” The interactive television program guide will then redirect the use of the second tuner and process the secondary function request. If the user desires to continue the recording process, the user will select “No.” The interactive television program guide will then cancel the secondary function request and allow the user to continue using the second tuner for recording the selected program.
• FIG. 5. shows the first of four illustrative configurations involving a single-tuner set-top box500 that has an RF bypass switch. If desired, the functions of the RF bypass switch may be provided by a digital switch. The RF bypass switch may be incorporated as part of the input circuitry on either the viewing or recording devices and functionally perform the same asRF bypass switch502.RF bypass switch502 allowsraw cable input506 to be passed through to an external device such astelevision116 without being processed.RF bypass switch502 not only receivesraw signal506, but it receives processedsignal508 as well.Processed signal508 is output fromtuner504 and intoVCR114.Processed signal508 passes throughVCR114 and is output as processedsignal510 fromVCR114 toRF bypass switch502. The interactive television program guide command signals online212 are also an input toRF bypass switch502 and are used to controloutput512 ofRF bypass switch502.Output512 fromRF bypass switch502 may be eitherraw signal506 or processedsignal510. The ability ofRF bypass switch502 to output either the raw or the processed signal is an attractive feature because it allows the user to view programs on channels that must be processed by a tuner for unscrambling or decoding, such as HBO, as well as those programs that do not.
• When the interactive television program guide system is in watch-and-record mode, onlyraw signal506 is transmitted onoutput512 ofRF bypass switch502 and directed totelevision116.Output508 oftuner504 in set-top box500 is directed toVCR114 only. Therefore, all of the programs (scrambled and unscrambled) that are available to the user fromtelevision distribution facility110 may be recorded byVCR114. Whentelevision116 receives unprocessedraw signal506, the user may view all of the programs available to that user fromtelevision distribution facility110 that do not require processing or unscrambling bytuner504. The user may tune the television by usingremote control118 to change the channels on the television and not by changing the channels on set-top box tuner504. The interactive television program guide may process channel requests received fromremote control118 and may retransmit suitable channel changing commands toTV116 usingIR transmitter200. In this mode, channel requests are redirected away fromtuner504, which is normally the recipient of such requests, to the tuner oftelevision116.
• Whentelevision116 is in a mode where it is receivingraw signal506, use of the interactive television program guide is limited because many of the interactive television program guide's features require processing by set-top box tuner504 and itsoutput508 to be directed totelevision116. However, limited use of the interactive television program guide is still possible in this mode because some interactive television program guide features remain accessible to the user. For example, the interactive television program guide may display simple information such as the channel number on the front panel of the set-top box. The interactive television program guide may also prevent the user from attempting to tune to any channel thattelevision116 cannot decode due to scrambling. The interactive television program guide may provide the user with the option to select the last channel viewed, use favorite channel features or adjust television volume without interrupting the recording process. If the user had set a reminder for the time during which a recording is active, the interactive television program guide may automatically tune the television to the selected program. Alternatively, the interactive television program guide may allow the user to toggle between programs with reminders, by using a predefined key onremote control118. If the user attempts to tune to a program that is parentally controlled, the interactive television program guide may prevent the transmission of channel-tuning commands to the television. In this case, the interactive television program guide may tune to the desired program only after a special personal identification number (PIN) is entered intoremote control118. The interactive television program guide may present a prompt for such a PIN on the front-panel display of set-top box500. Interactive television programguide command signal212 is an input toIR transmitter200 and is used to send commands from the interactive television program guide to external devices such astelevision116 andVCR114 via infrared transmission signals.IR transmitter200 may be optimally positioned so thatVCR114 andtelevision116 will receive the IR signal effectively.
• The single tuner, RF bypass switch configuration ofFIG. 5 operates in a similar manner to the two-tuner set-top box configurations described inFIGS. 2(a) and2(b) in that it allows the user to watch one program while simultaneously recording another.
• FIG. 6 is a flow chart of steps involved in using an interactive television program guide system that includes a single tuner, RF bypass switch, and set-top box tuner output directed toVCR114 as shown inFIG. 5. Atstep300, the interactive television program guide provides the user with an opportunity to select a program to be recorded at some later time. After the user selects a program for recording, the interactive television program guide continues to direct set-topbox tuner output508 totelevision116 at step600 until the recording process has been initiated. Directing set-topbox tuner output508 ofFIG. 5 totelevision116 allows the user to view all programming available fromtelevision distribution facility110.
• At step602, the interactive television program guide initiates the recording of the selected program by directing set-topbox tuner output508 toVCR114. The interactive television program guide tunes set-top box tuner504 to selected program and sets set-topbox tuner output508 to an optimal volume level for recording. Because set-topbox tuner output508 is being used to record the selected program, all programs available to the user fromtelevision distribution facility110 may be recorded. When the recording process is initiated, the interactive television program guide directsraw signal506 throughRF bypass switch502 and totelevision116. Becausetelevision116 receivesraw signal506 while the recording process is occurring only programs decodeable by cableready television116 may be viewed. The interactive television program guide may send commands viaIR transmitter200 to tunetelevision116 to the channel previously watched by the user so as not to interrupt the program being viewed. Whiletelevision116 receivesraw signal506, the user has limited access to interactive television program guide features because to have full access to interactive television program guide features set-top box tuner504 must not be in the record mode.
• At step604, without interrupting the recording process, a user may select a particular television channel by usingremote control118. When the user selects a channel, the interactive television program guide sends IR commands to the tuner oftelevision116 and not to set-top box tuner504, thereby providing an interruption-free recording environment. In this configuration, the user may use a limited number of interactive television program guide functions such as parental control, reminders and volume control.
• At step606, when the selected program ends, the interactive television program guide sends IR commands to stop the recording process. The interactive television program guide directs the output of set-top tuner504 totelevision116 and also tunes set-top box tuner504 to thechannel television116 was previously tuned to, which once again provides the user with the full range of programs available to the user and full access to interactive television program guide features. The interactive television program guide may change the volume of set-topbox tuner output508 back to the volume level selected by the user.
• FIG. 7 is the second illustrative configuration of the single tuner and RF bypass switch set-top box system. Set-top box500 is similar to that shown inFIG. 5. However, here,output508 oftuner504 is directed totelevision116 andoutput512 ofRF bypass switch502 is directed toVCR114. RFbypass switch output512 is controlled by interactive television program guide command signals online212, which are an input toRF bypass switch502. In this configuration, if a user wanted to watch one program while recording another,VCR114 is only able to record programs that can be decoded by the VCR (e.g., unscrambled and unprocessed analog channels). However, the user would also be able to view any program available to the user while simultaneously recording a selected program that is different from the program being viewed. If the user is not viewingtelevision116 any program available to the user may be recorded. The user may also view a scrambled program if that program is the same one being recorded. In addition, unlike in the first configuration of the single-tuner RE-bypass set-top box system shown in FIG.5, the user would be able to use and enjoy the full range of available interactive television program guide features. The full range of interactive television program guide features may be used simultaneously with the recording function because set-topbox tuner output508 is input directly totelevision116. In contrast to the set-top box embodiment shown inFIG. 5, where set-top box output508 is directed toVCR114 and full interactive television program guide use is not possible while in the watch and record mode, this single-tuner RF-bypass-switch embodiment does not interfere with the functionality of the interactive television program guide whenVCR114 recording function is in operation because set-topbox tuner output508 is directed totelevision116 and notVCR114.
• FIG. 8 is a flow chart of steps involved in using an interactive television program guide system that includes a single-tuner RF-bypass switch, and set-topbox tuner output508 that is directed to a television as shown inFIG. 7. Atstep300, the interactive television program guide provides the user with an opportunity to select a program to be recorded at some later time.
• Atstep800, after the user has selected a program to be recorded, the interactive television program guide continues to direct set-topbox tuner output508 totelevision116 and switchesraw signal506 throughRF bypass switch502 toVCR114.
• Atstep802, when the selected program is to begin, the interactive television program guide initiates recording of the selected program. The interactive television program guide sends IR commands that tune the internal tuner ofVCR114 to the desired channel for the selected program. This configuration of the present invention allows only programs that are decodeable byVCR114 to be recorded while another program is being viewed and not those programs that require processing or unscrambling by set-top box tuner504. However, iftelevision116 is not being viewed,VCR114 can record any program available to the user. While the recording process is occurring, set-topbox tuner output508 continues to be directed totelevision116 providing the user with unlimited access to interactive television program guide features and all programs available to the user fromtelevision distribution facility110.
• Atstep804, when the selected programs ends, the interactive television program guide sends IR commands toVCR114 to stop the recording process. The interactive television program guide also switchesraw signal506 and processedsignal508 such thatVCR114 receives processedsignal508 once again.
• FIG. 9 shows a diagram of a third illustrative configuration involving a single-tuner RF-bypass-switch system. In this configuration or pass through mode,RF bypass switch900 has twooutputs902 and904 and includes switching circuitry that provides the user with the ability to pass its twoinputs506 and508 directly tooutputs902 and904 respectively. In addition, outputs902 and904 ofRF bypass switch900 may be switched or placed in a switched mode to receive a signal frominputs508 and506 respectively, upon commands sent from the interactive television program guide via the interactive television program guide command signals online212. This switching capability allows the interactive television program guide to direct eitherraw signal506 or processedsignal508 to eitherVCR114 ortelevision116. In normal mode,raw signal506 is directed toVCR114 viaoutput902 and processedsignal508 is directed totelevision116 viaoutput904. However, ifVCR114 is unable to record the selected program because the program's signal is scrambled or digital, the interactive television program guide will send commands vialine212 toRF bypass switch900 to switchraw signal506 totelevision116 viaoutput904 and processedsignal508 toVCR114 viaoutput902. This switch arrangement allows the user to record the selected program while simultaneously watching another program that does not require processing bytuner504.
• FIG. 10 is a flow chart of steps involved in using an interactive television program guide system that includes a single-tuner RF-bypass switch that can operate in two modes, pass through or switched, as shown inFIG. 9. Atstep300, the interactive television program guide provides the user with an opportunity to select a program to be recorded at some later time.
• Atstep1000, the interactive television program guide directs set-topbox tuner output508 throughRF bypass switch900 viaoutput904 totelevision116 andraw signal506 throughRF bypass switch900 via902 toVCR114. A user may be watchingtelevision116.
• Atstep1002, when the program is scheduled to begin, the interactive television program guide initiates recording of the program selected by the user. The record process may be initiated while a user is watching programming ontelevision116.
• Atstep1004, ifVCR114 can decode the channel on which the selected program will be broadcast, the program continues to direct set-topbox tuner output508 totelevision116 andraw signal506 throughRF bypass switch900 toVCR114. The interactive television program guide sends IR commands to the internal tuner ofVCR114 that tune to the desired channel for the selected program and directsVCR114 to start recording the selected program. This allows the user to view any program available to the user fromtelevision distribution facility110 without any interruptions due to the recording process.
• Atstep1006, ifVCR114 cannot decode the channel on which the selected program will be broadcast, the interactive television program guide redirects set-top box output508 fromtelevision116 toVCR114 and also redirectsraw signal506 throughRF bypass switch900 fromVCR114 totelevision116. The interactive television program guide may set set-topbox tuner output508 to an optimal volume level for recording. The interactive television program guide sends commands online212 to tune set-top box tuner504 to tune to the channel on which the selected program will be broadcast. The interactive television program guide also sends IR commands totelevision116 to tune it to the channel, if unscrambled, that the user was viewing prior to the switch. This provides the user with the ability to record any program available to him fromtelevision distribution facility110. However, the user may only view programs decodeable by cable-ready television116. Similar to the configuration described inFIG. 5 in this configuration whentelevision116 is in a mode where it is receivingraw signal506, use of the interactive television program guide is limited because many of the interactive television program guide's features require processing by set-top box tuner504 and itsoutput508 to be directed totelevision116. However, limited use of the interactive television program guide is still possible in this mode because some interactive television program guide features remain accessible to the user. See description forFIG. 5.
• Atstep1008, when the selected programs ends, the interactive television program guide sends IR commands toVCR114 to stop the recording process. The interactive television program guide switchesraw signal506 and processedsignal508 so thatraw signal506 is directed toVCR114 and processedsignal508 is directed totelevision116 once again. The interactive television program guide may tune set-top box tuner504 to the channel that was being viewed prior to the switch to provide the viewer with an interruption-free viewing environment.
• FIG. 11(a) showsRF bypass switch1100 in one of three possible positions.RF bypass switch1100 may be used in place ofRF bypass switch900 ofFIG. 9 in a single-tuner RF-bypass-switch interactive television program guide system. When this substitution is made, a very versatile configuration of the single-tuner RF-bypass-switch interactive television program guide system results.FIG. 11(a) showsRF bypass switch1100 in its normal position. The normal position allows processedsignal508 from set-top box tuner504 to be output from both RFbypass switch outputs1102 and1104 to be directed toVCR114 andtelevision116, respectively.
• FIG. 11(b) shows another switch position ofRF bypass switch1100. This position allowsinputs506 and508 to be passed directly throughRF bypass switch1100 tooutputs1102 and1104, respectively.
• FIG. 11(c) shows another switch position ofRF bypass switch1100. This position allowsinputs506 and508 to be switched tooutputs1104 and1102, respectively.
• FIG. 12 shows a diagram of a fourth illustrative configuration of the single-tuner RF-bypass-switch set-top box interactive television program guide system. TheFIG. 12 configuration uses RF bypass switching circuitry1100 (shown inFIG. 11), which is more complicated than RF-bypass switching circuitry900 (shown inFIG. 9). In this embodiment, the RF bypass switch provides the user with three distinct combinations for the two outputs. These three distinct combinations are as follows: 1) both theoutputs1102 and1104 transmit processedsignal508 toVCR114 andtelevision116 respectively; 2)output1102 transmitsraw signal506 toVCR114 andoutput1104 transmits the processedsignal508 totelevision116; and 3)output1102 transmits processedsignal508 toVCR114 and theoutput1104 transmitsraw signal506 totelevision116. In the normal mode, bothVCR114 andtelevision116 receive processedsignal508 from the set-top box tuner504. The normal mode may be used to simultaneously watch and record, but the program watched by the viewer must be the same as that being recorded. If different programs are watched and recorded and the program selected to be recorded is unscrambled or can be decoded byVCR114, the interactive television program guide switchesoutput1102 of RF-bypass switch1100 to a position such thatVCR114 can receiveraw signal508. In this situation,television116 continues to receive the processed signal from set-top box tuner504, which gives the user unrestricted access to all programs available to the user, in addition to the unrestricted use of the interactive television program guide and its many features. The user is able to watch one program while recording another. If the selected program cannot be unscrambled byVCR114, the interactive television program guide will send commands toRF bypass switch1100 that command processedsignal508 to be directed toVCR114 andraw signal506 to be directed to the television. In this switching position, the user is restricted to viewing programs that do not require unscrambling or processing by set-top box tuner504.
• FIG. 13 is a flow chart of steps involved in using the interactive television program guide system shown ofFIG. 12, which includessingle tuner504 and the substitutedRF bypass switch1100 shown inFIG. 11 that can operate in three modes.
• Atstep300, the interactive television program guide provides the user with an opportunity to select a program to be recorded at some later time.
• Atstep1300, the interactive television program guide directs set-topbox tuner output508 totelevision116 and toVCR114. This arrangement is the normal switching position for this configuration of the present invention.
• Atstep1302, the interactive television program guide initiates recording of the program selected by the user.
• Atstep1304, while the user is viewingtelevision116, ifVCR114 can decode the channel on which the selected program will be broadcast, the interactive television program guide continues to direct set-topbox tuner output508 totelevision116 andraw signal506 throughRF bypass switch1100 toVCR114. The interactive television program guide sends IR commands that tune the internal tuner ofVCR114 to the desired channel for the selected program and that directsVCR114 to start recording the selected program. This allows the user to view any program available to the user from his cable company without any interruptions due to the recording process.
• Atstep1306, while the user is viewingtelevision116, ifVCR114 cannot decode the channel on which the selected program will be broadcast, the interactive television program guide redirects set-top box output508 fromtelevision116 toVCR114 and also redirectsraw signal506 throughRF bypass switch1100 fromVCR114 totelevision116. The interactive television program guide may set set-topbox tuner output508 to an optimal volume level for recording. The interactive television program guide may tunetelevision116 to channel previously selected by the user. This provides the user with the ability to record any program available fromtelevision distribution facility110. However, the user may only view programs decodeable bycable television116. As mentioned previously in the specifications forFIGS. 5 and 10, whentelevision116 is in a mode where it is receivingraw signal506, use of the interactive television program guide is limited because many of the interactive television program guide's features require processing by set-top box tuner504 and itsoutput508 to be directed totelevision116. However, limited use of the interactive television program guide is still possible in this mode because some interactive television program guide features remain accessible to the user.
• Atstep1308, when the selected programs ends, the interactive television program guide sends IR commands to the VCR to stop the recording process. The interactive television program guide switchesraw signal506 and processedsignal508 so that processedsignal508 is directed to bothVCR114 andtelevision116. The interactive television program guide may tune set-top box tuner504 to channel selected prior to the switch.
• The interactive television program guide system provides the user with a variety of watch and record options that depend on the particular signal switching options, tuner capabilities, and tuner functions available inuser television equipment106. The interactive television program guide system may use various types of switches to implement the necessary signal routing between user program guide equipment tuners, the viewing device tuner and the recording device tuner. A switch may have one or more outputs depending on the interactive television program guide system's configuration. Thus, signal switching options relate to the switching capabilities associated with a particular type of switch. Tuner capabilities relate to whether a tuner is capable to decoding a scrambled television input signal, or a digital signal. For example, when a user requests to view a scrambled program the interactive television program guide allocates a tuner that is capable of decoding the scrambled signal such as a set-top box tuner, and does not allocate a tuner such as a viewing device tuner that may be incapable of decoding the signal. The allocated tuner provides a corresponding unscrambled or processed signal toviewing device116 so that the user is able to view the requested program.
• A tuner that is “less capable” of fulfilling a user request is a tuner that is capable of handling the user request. For example, a viewing device tuner may be capable of handling a user request to view an unscrambled program. In that case the interactive television program guide will not allocate a tuner that is capable of unscrambling signals such as a set-top box tuner, because it is not necessary to do so.
• Tuner functions relate to the various user-requested and non-user-requested automatic functions that a tuner can perform. Tuner functions, also referred to as secondary functions include providing the user with the ability to view and to record selected television programs using the interactive television program guide, collect data from the television input signal while another tuner is performing another function, supporting Internet browsing, providing the user with the capability to play a particular music channel or to obtain music information, providing the user with interactive services, performing a background process or providing a second video image (PIP).
• Another option provided to the user by the interactive television program guide is the watch option. The watch option allows the user to immediately view a selected program if the program is currently being broadcast when the user selects it from a group of interactive television program guide program listings or if the program will be broadcast in the future, the watch option allows the user to set a reminder that will remind the user that the selected program is about to begin. The user may set a reminder that will displayed while the viewer is watching a television program or the user may set the reminder to automatically tune to the selected program when it is time for that program to begin.
• While a user is viewing or attempting to view a particular program the interactive television program guide will allocate tuner resources that are composed of one or more tuners for the viewing activity. The interactive television program guide may allocate tuner resources based on an assumption that the user is always viewing a particular program or that the user desires to view a particular program.
• In the case where a user is initially watching and recording the same program, then while the recording is still continuing the user desires to watch a different program, the interactive television program guide may allocate another tuner to accommodate the user's request in accordance with the configurations of the present invention described above.
• The optimal volume feature is a feature that allows the interactive television program guide to automatically set the output of a tuner that has been allocated for recording to its optimal volume level some time prior to the start of the recording process.
• The parental control feature is a capability of the interactive television program guide to prevent access to programs or channels that the user desires to block access to unless a special access code or personal identification number (“PIN”) is entered into the interactive television program guide system. After the PIN is entered into the system by the user, the user program guide equipment provides user feedback on a numeric display. The user feedback may be in the form of a user prompt, an indication that the correct or incorrect PIN has been entered, dashed lines or some other suitable method of providing the user with feedback.
• Interactive television program guide features include tuner functions such as watch and record, PIP, etc., or non-tuner based features such as providing the user with program listings, program information displays and on-screen menu displays, etc.
• The foregoing is merely illustrative of the principles of this invention and various modifications can be made by those skilled in the art without departing from the scope and spirit of the invention.
